Supreme Court decision gives states power to tax online purchases

In a decision that will have a sweeping impact on the taxation of Internet sales in the US, the Supreme Court upheld the right of South Dakota (and thus, all states) to require online retailer Wayfair, Inc. (and thus all out-of-state retailers) to collect sales tax from a South Dakota resident buyer and to remit such tax to the State of South Dakota, even though Wayfair, Inc. has no physical presence in the state of South Dakota.
